It has spread slowly and has been named the Lerner Virus. It affects only computers that hold e-mails from Lois Lerner who is suspected of being the author of the malware. It seems to wait for queries for Lerner e-mails, then retroactively destroys the hard drive of the affected computer.
Interestingly it seems to be able to destroy hard drives as much as 3 years in the past. The time-traveling aspect of the virus is what separates it from most others.
